  • 22. Total pressure = 720 mm Hg, Gas 2 = 93 mm Hg, Gas 3 = 330 mm Hg
  • 23. Total pressure = 9000 mm Hg, Gas 2 = 89 mm Hg, Gas 3 = 3000 mm Hg
  • 24. Total pressure = 760 mm Hg, Gas 2 = 4 mm Hg, Gas 3 = 240 mm Hg
  • 25. Total pressure = 435 mm Hg, Gas 2 = 3 mm Hg, Gas 3 = 145 mm Hg
Ideal Gas Law
Determine the unknown quantity for each problem. Staple your work to the back.
  • 26. What pressure will be exerted from 0.50 moles of a gas contained in a 1.00 L flask at 25.0 °C?
  • 27. Find the number of moles of a gas if 1.0 L of it at 15.0 °C has a pressure of 5 atm.
  • 28. What volume will be occupied by 1.35 moles of a gas at 100 °C and 2.58 atm of pressure?
  • 29. Calculate the value of the gas constant (R) using STP, one mole of gas, and the volume for one mole of a gas (22.4 L).
  • 30. What will be the pressure of 0.010 mol of oxygen gas in a 4.5 L flask at a temperature of 104 °C?
Ideal Gas Law (pt 2)
Determine the missing data. Assume all gases are dry. Staple your work to the back. Don’t forget to use Kelvin temperatures. ST = Standard Temperature = 273 K. SP = Standard Pressure =1 atm
